T 0 all whom it may concern."

Be it-known that I, SAMUEL P. SADTLER, a

citizen of the United States, residing at Germantown, Philadel hia, inthe county of tate of Pennsylvania, have invented certain new and usefullm- 'rovements in Compositions forRemoving specification.

This invention relates to a preparation for removing paint, varnish,&c., from wood,

metal and .other surfaces without injury thereto. v

The reparation consists primarily of acetone oi which is the essentialand active ingredient. By acetone oil I mean the mixture of ketoneswhich is obtained as a byproduct along with acetone in the preparation Iof the latter and which is separated in the purification of the acetone.

While acetone oil is a powerful solvent, it has been found to operatemore quickly and thoroughly when combined with one or more otherchemicals which are, preferably, also solvents. Benzol, toluol andeither wood or grain alcohol may be advantageously comined. with theacetone oil, and when the same are used a desirable formula for thecomposl'tlon 1s-acetone 011 two parts; benzol, one part; toluol, onepart; and a mixing agent-much as alcohol, one part, the same being'thoroughly mixed by agltation.

Either benzol or toluol may be used to the I exclusion of the other,though it is preferable to employ both. Benzol is more costly thantoluol, whereas the objectionable odorv of toluol is neutralized whencombined with b enzol. In addition to its qualities as a sol-.

dients in making a permanent, water-clear solution as it mixes orcombines with the water separated by the benzol or toluol. Thecomposition does not evaporate rapidly, remaining on the surface towhich it is applied sulliciently long to loosen or raise the paintvarnish or other m atter,so that when wiped off the surface isabsolutely clean and may if d esired be immediately refinished.

As I believe myself to be the first to emloy acetone oil in acomposition for removmg paint, varnish, etc, the invention is notrestricted in the matter of the other ingredi- 5. A composition forremovin paint or varnish containing acetone oil, toluol, and a mixingagent.

In testimony whereof I allix my signature in presence of two witnesses.I
